Spectrofluorometry of Essential Oils: Bergamot Oil
No full textBergamot (Citrus bergamia, Risso et Poiteau) cultivation started in Italy at the beginning of the 18th century. Italian bergamot production is limited in a narrow strip of the Calabrian coast, along the Ionian and the Thyrrenian seas. Bergamot is cultivated for the essential oil representing an important raw material for cosmetic and food industry.
Among non-volatile fraction components of the bergamot essential oil there are coumarins, whose fluorescence was widely investigated in the past. Because of their structural diversity and diverse occurrence, these oxygenated heterocyclic compounds have an important role in the identification of the quality and genuineness of the bergamot essential oil.
This review reports spectrofluorometric properties of bergamot essential oil. From excitation-emission matrix (EEM) analysis of bergamot essential oil solutions in ethanol characteristic emissions of citropten, linalyl acetate and that of chlorophills have been detected. One citropten emission has been used in quantitative determination while none of linalyl acetate.
Quantitative fluorometric determination of citropten gives the sum of both citropten and 7-methoxy-5-geranyloxy-coumarin concentration
